I had to shave the subject for space. What I mean is: What internally installed computer peripherals typically need to be connected to the internal power source? In my current system, I know all my drives (hard, floppy, cd) are connected to the power source, but not the video card, sound card, etc.
I ask because I am going to be buying a new system. I am not sure whether to get the default tower configuration with the 250 watt power supply, or a slightly more expensive one with a 300 watt supply.
For the record, the system is going to be packaged with a CD-RW drive, hard drive, integrated sound and video, an ethernet adapter, and modem. I will be adding my own monitor, keyboard, mouse, floppy disk drive, 2nd hard drive, scanner, and printer, and in the future, a G.Lite ADSL modem, possibly a third hard drive, a DVD-Rom or DVD-Ram drive, a tv capture card such as the ATI All-In-Wonder, a joystick, and a pc video camera.
I know that scanners, printers and monitors can be plugged in at an outlet. Mice, keyboards and joysticks don’t need a power source. I am sure the DVD drive and hypothetical third HD will. I am uncertain about the All-In-Wonder, the video camera, and the ADSL modem.
Would a 250 watt power supply be enough for all this stuff? Or would I have to make something external?
